Heat a saute pan over medium heat until it just starts to smoke.
Add canola oil, garlic, thyme and cook for about 1 minute. Add onions, salt,
pepper and cook until onions are a light brown. Deglaze pan with
worcestershire, add butter and continue cooking until they attain a dark brown
color. Reserve for later use.

To make the cheese: combine garlic, cream cheese and butter in a
food processor and process till well combined. Add fresh herbs and process till
just combined. Season to your taste with salt and pepper.

Pre heat your grill to medium heat ( Due to the fat content of the
wagyu the burgers will char pretty quickly on high heat).Season wagyu beef with
salt and pepper. Form into 4 ounce patties. Brush the insides of the burger
buns with melted butter and toast on the grill. Cook burgers 3-4 minutes on
each sides for medium rare.

To assemble: coat both sides of the bun with cheese, put the
burgers on the bottom bun and top with onions.
